  • Patent number: 6054431
    Abstract: The present invention relates to methods of treating gram-positive bacterial infections by administration of a BPI protein product alone, or in combination with an antibiotic. BPI protein product alone has a bactericidal or growth inhibitory effect on selected gram-positive organisms. BPI protein product also increases the susceptibility of gram-positive organisms to antibiotics and can even reverse resistance of gram-positive organisms to antibiotic.
